I think it was this version of the Titanic story that caused a controversy over the tune that was played for (supposedly) the last song that the on-ship band played (again, supposedly “Nearer My God To Thee”). Clueless Americans got upset because it was the “wrong tune”. It was not the tune that Americans are familiar with. The movie makers used the tune that the British are familiar with. Since the ship was a British vessel and the band was British, it was probably the “right tune”.
